PLOW.

Specification ofLetters Patent.

Patented Apr. 3, 1917..

To all whom it may concern."

Be it known that I, LOUIS VVIARD, a citizen of the United States, residing at Batavia, in the county of Genesee and State of New York, have invented new and useful Improvements in Plows, of which the following is a specification.

This invention relates to plows which are more particularly designed for very heavy work such as is usually done by contractors and road builders when tearing or ripping up old roads or hardened surfaces of the ground preparatory to laying new pavements or road beds on the same. Such plowin g is usually much more difficult than turning of soil for agricultural purposes and subjects the plow to extraordinary strains which the usual farm plow is unable to withstand.

The objects, therefore, of this invention are to provide a heavy duty plow in which the beam of the stock is so constructed that the same is reinforced or straightened at the points where it is subjected to the heaviest strains so as to avoid breakage of the same; also to so construct the landside that the bolts or other fastenings whereby the same is connected with the standard of the stock will be relieved of the shearing strains and thereby prevent the landside from being broken or torn off from the stock while the plow is in use; also to so combine the plow point with the landside that the same may be made of a material which is capable of resisting wear to a greater extent than has been possible in the plows as heretofore constructed; and also to combine the landside with two plow points at its opposite ends and permitting the same to be reversed end for end so that when one of these points becomes worn out it can be replaced by the other point and thereby enable the plow to be used for a longer time before necessitating interruption in its use while repairing the same.

In the accompanying drawings:

' Figure 1 is a side elevation of the plow embodying my improvements viewed from the landside thereof. Fig. 2 is a top plan view thereof. Figs. 3, l and 5 are fragmentary horizontal sections of the plow taken in the correspondingly numbered lines in Fig. 1. Figs. 6, 7 8 and 9 are vertical sections, on an enlarged scale, taken in the correspondingly numbered lines in Fig. 1. Fig. 10 is a detached fragmentary vertical transverse section of the standard taken on the same line as Fig. 6. Fig. 11 is a detached vertical transverse section of the landside plate taken on the same line as Fig. 6.

Similar characters of reference indicate corresponding parts throughout the several views.

In its general organization this plow comprises a stock consisting of an upright standard 1 and a horizontal beam 2 projecting forwardly from the upper end of the stand ard, handles 3 connected with the standard and beam, a landside plate 4 mounted lengthwise on the landside of the standard and provided at its front and rear ends with plow points 5, 6, a shoe 7 supporting the rear plow point and mounted on the rear part of the standard, a shin-piece 8 mounted on the standard above the landside plate, a wing 9 mounted on the lower front part of the standard on the furrow side of the same and a mold board 10 mounted on the upper rear part of the standard on the furrow side of the same.

The standard 1 and the beam 2 forming the support of the plow are preferably constructed in one piece by casting the same of steel so as to render the same strong and durable and enable these parts to withstand the heavy strains to which the same are subjected while plowing up roads or other hard surfaces. Owing to such strains the stocks of plows have heretofore been frequently broken at the junction between the rear end of the beam and the upper end of the standard and in order to avoid this the beam of the present plow is so constructed that its several members are heaviest at the points which are subjected to thegreatest strain and lightest at such points where the same are subjected to lesser strains. For this purpose the vertical web 11 of the beam is gradually increased in height and in thickness from its front end toward its rear end, as shown in Figs. 1, 8, 8 and 9, and the laterally projecting flanges 12, 13 arranged lengthwise on the upper and lower edges of the beam are also gradually increased in thickness vertically as well as increased in width horizontally from the front end of the beam toward the rear end thereof, as shown in Figs. 2, 3, 8 and 9. It will be manifest from this construction of the beam that the size or cross section of the web and flange gradually become greater from the front parts thereof I the plow points may be arranged in front of.

'where the strain is less severe to the rear parts thereof where the strain is mostintense and that the beam will therefore be strongest at its rear end where it joins the 7 upper end of the standard and is subjected to the greatest breaking strains and less strong toward its front end in which direction the strains to which the beam is subjected become gradually less severe. By this judicious distribution of the material in the I beam it is possible to makethe same stronger where provision against breakage is most needed Without unduly increasing the weight of the plow as a whole and without materiallyincreasing the cost of the same.

"As shown in Figs. 1, 4 and 5, the landside plate and the two plow points are preferably constructed of onepiece and the same are so mounted on the standard that they may be reversed end for end so that either one of the standard and take the main or initial wear in the act of plowing up the road,

metal or material which'is very strong and durable and has the capacity of resisting hard wear. The landside plate and plow points are mounted on the standard by providing the latter on its landside with a recess or seat. having a fiat vertical face 14 which engages with the inner flat side of the landside plate and the rear plow point and downwardly facing shoulder 15, engaging with the upper edge of the landside plate and a downwardly facing shoulder 16 engaging withthe upper edge of the rear plow V point,,as' shown in Figs. 1, 5 and 7 The 7 bolts 17 passing transversely through bolt formed: respectively on these parts.

landside plate and the plow points are preferably secured to therstandard by horizontal holes18, 19' in. the landside plate and the adjacent lower portion of the standard, three of such boltsbeing shown for-this purpose in the drawings although any other suitable number may be employed, if desir d. In

order to relieve these bolts from the shear ing strains to. which the same are subjected as the front plow point enters the ground the cooperating surfaces of the standard and the landside plate are provided with interlocking= complementary projections and recesses In the preferredform of the means for relieving he sh ar g s rains on these bolts a. hollow conical boss 20 is formed on the vertical face of the seat of the standard around each of the bolt holes and engages with a corresponding shaped recess or seat 21 formed on the opposing inner side of the landside plate around the inner end of the companion bolt hole therein as shown in Figs. 5 and 6. In order to permit of reversing the landside plate and its plow points end for end and still utilize the same means for fastening these parts together and also protect the bolts against shearing strains, these bolts, the bosses around the same and the bolt holes in the landside plate are arranged symmetrically, the opposite ends of each bolt hole are provided with conical seats '21 and the heads 22 of the bolts are likewise made of conical form. As shown in the drawings, the three bolts, the corresponding bolt holes and the bosses are arranged so that two sets of these are arranged horizontally in line adjacent to the lower portions of the standard and the landside plate and equidistant from opposite sides of the vertical center of the landside plate and the third bolt, hole and boss are arranged adjacent to the upper part of the landside plate and in line with the vertical center of this plate. By this arrangement the landside plate and its plow points may be reversed end for end without requiring any change in the means of fastening the same to the standard and without any alteration in the means of interlocking the stand ard with the landside plate inasmuch as the conical recesses or seats on one side of the landside plate receive the bosses and the conical heads of the bolts engage with the conical recesses on the other side of the plate in one position of the latter and the plow points, while in the reverse position of the landside plate and plow points those recesses which were previously engaged by the bolt heads are now engaged by the bosses and those recesses which were previously engaged by the bosses are now engaged by the. conicalheads of the bolts.

It -will= thusbe apparent that the landside plate and its points may be readily reversed end for end for bringing either of the points into the working position and; enable one plow point to be worn out after another, whereby the time during which the plow may be used before repairing its points may be doubled, thereby reducing interruption in the use of the plow formaking repairs.

In order to permit the plow points to always hug or press against the landside of the furrow the sharpened ends of these points are turned toward the landside of the furrow when in their operative forwardly pointing position as shown in Figs. 4 and 5. In order to accomplish this the outer end 23 of one plow point is turned laterally in one direction and the outer end 2%- of the other plowpoint. is turned in the opposite direction, as shown in Figs. 4: and 5, whereby the landside plate and its points may be freely reversed end for end and each point will be turned laterally toward the landside when shifted into its operative position at the front of the standard.

In order to relieve the wear on the underside of the rear or trailing plow point which for the time being is not in use and also to tip the front or advancing plow point downwardly so as to enter the ground properly the shoe is so constructed that it projects downwardly below the rear edge of the rear plow point. For this purpose the shoe 7 is provided with a lower horizontal runner 25 arranged underneath the rear plow point and the rear portion of the standard, a fastening flange 26 projecting upwardly from the furrow edge of the runner and secured to the furrow side of the adjacent portion of the standard by means of a bolt 27, and a retaining flange 28 projecting upwardly from the landside edge of the runner and engaging with the outer face of the rear plow point, as shown in Figs. 1, 4, 5, 6 and 7 If desired, the landside plate may be only provided with a plow point at its front end and the rear point on the same may be omitted but in such a construction the advantage of a double not be obtained.

In case this plow is to be used for rooting up the soil or roadway without turning the soil or material in either direction to any plow point wear would material extent the wing 9 may be omitted and when thus altered a greater length of plow point is exposed to'the ground and operates more efiectively for tearing up the ground or roadway, this being particularly desirable when breaking up a hard roadway preparatory to repaving or re-surfacing the same.

My improved plow is particularly desirable for use by contractors or road builders whose work is of an unusually heavy nature and subjects the plow to extraordinary strains such as an ordinary. agricultural plow would not be able to stand.

My improved plow is therefore capable of performing this class of work without liability of being broken or wearing unduly and also without making the plow unnecessarily heavy so that the same can be readily manipulated.

I claim as my invention:

A plow having a support for a landside provided with a bolt hole and a boss around said hole, a landside which is reversible side for side and provided with a bolt hole and recesses on its opposite sides around said ,bolt hole, and a bolt for securing the landside to said standard, either recess adapted to [it said boss or said bolt head.

Witness my hand this 28th day of November, 1913.
